# This basically mounts $svcdir as a ramdisk, but preserving its content
# which allows us to run depscan.sh
# FreeBSD has a nice ramdisk - we don't set a size as we should always
# be fairly small and we unmount them after the boot level is done anyway
# NOTE we don't set a size for Linux either
# FreeBSD-7 supports tmpfs now :)
